I listened to it while working on a project using the Spring Framework and getting started with Boot. It was helpful because I was able to organize the concepts and mapping relationships that I had roughly learned while coding. 
However, for those who are completely new to Spring, the terminology may be unfamiliar and it may be a bit difficult to follow the flow. 

In my personal opinion, it is a lecture that feels more like skimming the table of contents of a huge book called Spring or reading the introduction than reading a complete book for beginners. 
If you are worried, I think it would be a good choice to listen to it all at once since the lecture time is short.

This course is for those who are new to the Spring framework. By looking at the code of the official Spring example project called Spring - PetClinic, you can easily and quickly understand the following core features of Spring.

Spring Introduction: Learning by Example (Revised Edition)

The purpose of this lecture is to give you a taste of what Spring does and how to use it in a short period of time using the official Spring example project that has already been created. If you were expecting an introductory lecture, it probably didn't meet your expectations. Thank you for your review. I will refer to it when I make an introductory lecture again next time. :)
